<h2>Detailed Description</h2>
<p>The QStyleOptionFrameV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.1 or above.</p>
<p>QStyleOptionFrameV2 inherits <a href="qstyleoptionframe.html">QStyleOptionFrame</a> which is used for drawing several built-in Qt widgets, including <a href="qframe.html">QFrame</a>, <a href="qgroupbox.html">QGroupBox</a>, <a href="qlineedit.html">QLineEdit</a>, and <a href="qmenu.html">QMenu</a>.</p>
<p>An instance of the QStyleOptionFrameV2 class has <a href="qstyleoption.html#type-varx">type</a> <a href="qstyleoption.html#OptionType-enum">SO_Frame</a> and <a href="qstyleoption.html#version-var">version</a> 2. The type is used internally by <a href="qstyleoption.html">QStyleOption</a>, its subclasses, and <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>() to determine the type of style option. In general you do not need to worry about this unless you want to create your own <a href="qstyleoption.html">QStyleOption</a> subclass and your own styles. The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement extensions without breaking compatibility. If you use <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>(), you normally don't need to check it.</p>
<p>If you create your own <a href="qstyle.html">QStyle</a> subclass, you should handle both <a href="qstyleoptionframe.html">QStyleOptionFrame</a> and QStyleOptionFrameV2. One way to achieve this is to use the QStyleOptionFrameV2 copy constructor. For example:</p>
<pre>     QStyleOptionFrame *option;

     if (const QStyleOptionFrame *frameOption =
            qstyleoption_cast&lt;const QStyleOptionFrame *&gt;(option)) {
         QStyleOptionFrameV2 frameOptionV2(*frameOption);

         <span class="comment">//</span> draw the frame using frameOptionV2
     }</pre>
<p>In the example above: If the <tt>frameOption</tt>'s version is 1, <a href="qstyleoptionframev2.html#FrameFeature-enum">FrameFeature</a> is set to <a href="qstyleoptionframev2.html#FrameFeature-enum">None</a> for <tt>frameOptionV2</tt>. If <tt>frameOption</tt>'s version is 2, the constructor will simply copy the <tt>frameOption</tt>'s <a href="qstyleoptionframev2.html#FrameFeature-enum">FrameFeature</a> value.</p>
<p>For an example demonstrating how style options can be used, see the <a href="widgets-styles.html">Styles</a> example.</p>

<h2>Member Type Documentation</h2>
<h3 class="flags"><a name="FrameFeature-enum"></a>enum QStyleOptionFrameV2::FrameFeature<br />flags QStyleOptionFrameV2::FrameFeatures</h3>
<p>This enum describles the different types of features a frame can have.</p>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QStyleOptionFrameV2::None</tt></td><td align="center" valign="top"><tt>0x00</tt></td><td valign="top">Indicates a normal frame.</td></tr>
<tr><td valign="top"><tt>QStyleOptionFrameV2::Flat</tt></td><td align="center" valign="top"><tt>0x01</tt></td><td valign="top">Indicates a flat frame.</td></tr>
</table></p>
<p>The FrameFeatures type is a typedef for <a href="qflags.html">QFlags</a>&lt;FrameFeature&gt;. It stores an OR combination of FrameFeature values.</p>
<h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionFrameV2::StyleOptionVersion</h3>
<p>This enum is used to hold information about the version of the style option, and is defined for each <a href="qstyleoption.html">QStyleOption</a> subclass.</p>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QStyleOptionFrameV2::Version</tt></td><td align="center" valign="top"><tt>2</tt></td><td valign="top">2</td></tr>
</table></p>
<p>The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement extensions without breaking compatibility. If you use <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>(), you normally don't need to check it.</p>
